I am just firing up an LH4 for the first time and I get 1 beep, then 3 beeps, then 3 more beeps, then 1 beep, then nothing. The LED (#5) on memory board B lights up after that, which is supposed to be an error in VRM 1/2 but I replaced that and it still does the same thing. I also swapped out the memory, and the processor, and I get the same message. Any help appreciated.
